The d iscussionw as made on the feasib ility of mi provin performance of cathod ic proces- ses by controllin the len th of three phase boundaries, and the su estionw as also proposed on possib ility to app ly the methods of controllin the len th of three phase boundary for the stud ies ofmeasurin , data- analyzin , modelin and assessin the as/ liqu id/metalmultiphase corrosion processes.
